LIGO detects gravitational waves from neutron stars colliding

Gravitational waves from the collision of two neutron stars have been detected for the second time ever — along with another, less certain signal that a neutron star being swallowed by a black hole.

It's Finally here. The First Ever Image of a Black Hole

The Event Horizon Telescope (EHT) has revealed the first-ever image of a black hole. The black hole in this image resides at the center of M87, a massive galaxy that’s in the Virgo cluster of galaxies.

Astronomers discover 83 supermassive black holes

Astronomers from Japan, Taiwan and U.S. have discovered 83 quasars powered by supermassive black holes in the distant universe, from a time when the universe was only 5 percent of its age.

Future Telescopes could Detect Starships Powered by Black Hole

Recent U.S. study suggests how surveys using gamma telescopes could find evidence of spacecraft powered by tiny artificial black holes. The concept of a black hole-powered spacecraft was first introduced by science fiction author Arthur C. Clarke.

Intermediate mass black hole found near galactic centre

The “quiet” black hole is located just 20 light years from the supermassive four-million-solar-mass black hole lurking at the centre of the Milky Way. In the future, it will fall into the supermassive black hole.

Gravitational-wave observatory LIGO set to double its detecting power

A planned US$35-million upgrade could enable LIGO to spot one black-hole merger per hour by the mid-2020s.

Scientists detect biggest known black-hole collision

An international team of scientists have detected gravitational waves from the biggest known black-hole collision that formed a new black hole about 80 times larger than the Sun.

First detailed observations of material orbiting close to a black hole

The novel GRAVITY instrument has discovered clumps of gas swirling around at about 30 per cent of the speed of light on a circular orbit just outside the innermost stable orbit of a four million mass black hole.

Astronomers spot signs of supermassive black hole mergers

This confirms the current understanding of cosmological evolution - that galaxies and their associated black holes merge over time, forming bigger and bigger galaxies and black holes.

Gamma rays seen from exotic Milky Way object

For the first time, an international collaboration of scientists has detected highly energetic light coming from the outermost regions of an unusual star system within our own galaxy.

Matter falling into a black hole at 30 percent of the speed of light

Astronomers report the first detection of matter falling into a black hole at 30% of the speed of light, located in the center of the billion-light year distant galaxy PG211+143.

Einstein's general relativity confirmed near black hole

Observations have for the first time clearly revealed the effects of Einstein's general relativity on the motion of a star passing through the extreme gravitational field very close to the supermassive black hole.

Aftermath of black hole consuming a star

For the first time, astronomers have directly witnessed the aftermath of a black hole consuming a nearby star, imaging the formation and expansion of a high-speed jet of material ejected in the maelstrom.

Mystery objects whizzing about in Milky Way’s core

Spectroscopic measurements of gas dynamics at the core of the Milky Way have revealed several unusual objects visibly whizzing around the supermassive black hole at the center of the galaxy .

Colliding neutron stars likely formed low-mass black hole

The merger of two neutron stars generated gravitational waves and high-energy gamma radiation and detected last August likely produced a record low-mass black hole.
